This invention pertains to heaters and has particularreference to certain improvements in hot air heaters of the type which is designed to be placed in the room to be heated and which includes an inner stove unit and an outer ornamental casing for housing the inner unit and for creating a circulation of air to be heated between said units. Ordinarily in this type of heaters, the outer casing is kept closed except when firing the same or removing the ashes so that the glow of the fire is hidden from view.

it is, therefore, the prime object of the present invention to so construct the outer casing that the same may, at the option of the user, be opened in such a ,manner as to expose the glow of the fire without disclosing the unsightly parts which are ordinarily visible when the outer casing of heaters of this type is opened. In other words, the invention comprehends a heater of this character which is constructed in such a manner as to provide an ornamental opening in its 7 outer casing in alineinent with the-transparent combustion chamber closure or door, which opening is provided with a closure capable of being either opened or closed and which when opened discloses the glow of the fire.

A further important object of the invention resides in the provision of a heater of this character which is so constructed that when the closure in the outer casing is opened, the circulation of the air to be beated is not afiected, whereby the device functions in the ordinary manner.

The invention further aims to provide an improvement in heaters of the character set forth, which is simple, inexpenslve and eficient.

With the above recited and other objects.

Fig. 2 is an enlarged fragmentary horizontal sectional view therethrough taken approximately on the line indicated at 2-2 in Fig. 1; i

Fig. 3 is an enlarged vertical sectional view therethrough taken approximately on the line 33 of Fig. 1.

Referring to the drawings by characters of reference, 10 designates an inner stove unit which includes a" combustion chamber 11, a tire box 12, and an ash pit 13. The combustion chamber 11 is provided with the usual opening 14 for firing the stove or introducing the fuel thereto and is" provided with a suitable closure, such as a pair of doors 15, which are hinged as at 16, said door having transparent paneled openings 17 through which the glow of the fire is visible.

in this type of heater, the inner stove unit is covered and concealed by the outer casing or housing ltisuitably spaced therefrom and provided with grille openings or gratings 19 to permit of the natural circulation of air between the inner stove unit and the outer casing so that cold air is drawn into the lower portion, heated and. expelled from above. In order to gain access to the closure doors 15 of the inner stove unit, the outer casing is provided with an opening 20 in alinement therewith, which practically consists of a pair of hinged doors 21.

In order to permit of the leaving of the doors in an opened condition to expose the glow of the fire to the occupants of the room in which the heater is arranged, and, at the same time, to conceal the unsightly parts of the inner stove unit and the air circulation spaces, the present invention comprehends .a means for concealing such unsightly parts which consists in providing the closuredoors 15, respectively, at their outer edges with lateral, forwardly-projecting angular extensions orv wings 22 extending beyond the hinges 16 to conceal the air-circulation space between. the inner and outer units. This means also includes a pair of grille elements or gratings 23 connected, respectively, to the upper and lower edges of the front wall of the outer casing WlllCh defines the opening, which grille plates or gratings are of an ornamental nature and extends 'angularly inward to a point adjacent the upper and lower edges of the closure doors 15. Under ther admit of the circulation of air to be heated which is taken in at the lower portion ofthe heater and discharges through the lower grille plate 23. The upper grille, plate will admit of an intake of air which will be. heated and thenceexpelled through the top grille-work or gratings 19.

From the foregoing it will thus be seen that an improvement in heating plants of this character has been devised, which permits the glow of the fire to be observed without disclosing the unsightly parts and without in any way affecting the circulation of the air to be heated.

-What is claimed is:

1. A heater including an inner heating unit having a fuel feed opening and a transparent closure, an outer casing unit having an opening alined with the fuel ,feed opening, anopaque closure for said. opening, and means provided respectively at the sides of the fuel feed closure and adjacent the top and bottom of the opening in the outer casing unit for concealing the remainder of the inner unit and the air-circulation spaces between the units when the outer casing closure is opened for the purpose of exposing the glow of the fire.

2. A heater including an inner heating unit having a fuel feed opening and a transparent closure an outercasing unit having an opening alined with the fuel feed opening, aclosure for said opening, and means provided respectively on the sides of the fuel feed opening closure and adjacent the top and bottom of the opening in the outer casing unit for concealing the remainder of the inner unit and the air-circulation spaces eo-mes closurexand grille elements at the top and bottom of the said outer casing opening.

3.4A heater, including an inner heating unit having a fuel opening and a closure, an outer casing spaced therefrom to define an air-circulation space therebetween and having an opening in alinement with the fuel feed opening, a closure for the opening in the outer casing, and means provided respectively on the sides of the fuel feed opening and adjacent the top of the o ening in .the outer casingfor concealing t e remainder of the inner unit and the air circulation space when the outer casing closure is openedto expose the glow of the fire, said means consisting respectively of angularly' disposed lateral and outer-extensions on the fuelfeed opening closure, said extensions having openings permitting of the circulation of air, and inclined grille elements at the top and bottom of said outer casing opening, the said' grille elements serving to permit of the, circulation of air when the outer casing is opened.

4. A heater including an inner heating unit having a fuel feed opening and a transparent closure and an outer casing unit having an opening alined with the fuel feed opening, a closure for said latter opening, and means located'adjacent the fuel feed opening for concealing the air circulation spaces between the units when-the outer cashaving openings permitting of circulation of air therethroug WILLIAM F.
